GAS SULFURIZED ANHYDRIDE CONVERTER IN SULFURIC GASEOUS ANHYDRIDE AND CATALYST SUPPORT FOR SAID CONVERTER

摘要

THE INVENTION CONCERNS A CONVERTER FOR TRANSFORMING GASEOUS SULPHURIC ANHYDRIDE INTO GASEOUS SULFURIC ANHYDRIDE. /P P THIS CONVERTER INCLUDES AN EXTERNAL ENVELOPE 12, A CENTRAL AND AXIAL TUBE 16 AND A CERTAIN NUMBER OF 14 ANNULAR BEDS. 1, 14-2, 14-3, 14-4 OF THE CATALYST ARE PLACED ONE ABOVE THE OTHERS AND SEPARATED BY PARTITIONS 20, 22, 24. THESE BEDS ARE BASED ON PLATES 18-1, 18-2, 18- 3, 18-4 OF SUPPORT WHICH, AS WELL AS THE PARTITIONS, HAVE AN INITIALLY BUCKET SHAPE SO THAT THEIR DEFLATION IS LIMITED DURING USE. THE FIRST CATALYST BED 14-1 IS PROVIDED AT THE LOWER PART OF THE CONVERTER 10 TO RECEIVE THE GAS CONTAINING SULPHUROUS ANHYDRIDE. /P P FIELD OF APPLICATION: SULFURIC ACID PRODUCTION.
